BACKGROUND

With the development of multimedia devices, such as smart televisions(TVs) and smart phones, users can enjoy various content services usingthe multimedia devices.

More particularly, a user can be provided with detailed contents ofinformation, which is provided through a video device such as a smartTV, through an additional device such as a smart phone. However, inorder to receive such services, the user must directly operate theadditional device to receive the detailed contents of the informationthat is provided through the video device, and this may causeinconvenience to the user. Further, since the user directly operates theadditional device to receive the detailed information on the informationthat is provided through the video device, viewing of an image that iscurrently reproduced in real time through the video device may beinterfered with.

For example, a user may be concerned about a character that appears in adrama while viewing the drama through a smart TV. In this case, the usercan manually input a search inquiry for the character in the drama,which is currently being reproduced on the smart TV, using a smartphone, and thus user convenience is deteriorated. Further, since thesearch inquiry for the character in the drama, which is currently beingreproduced on the smart TV, is manually input, the user's ability toconcentrate upon the viewing of the drama that is currently beingreproduced on the smart TV may be lowered.

The above information is presented as background information only toassist with an understanding of the present disclosure. No determinationhas been made, and no assertion is made, as to whether any of the abovemight be applicable as prior art with regard to the present disclosure.

FIG. 1 is a view of a service providing system for pictures in adisplayed image according to an embodiment of the present disclosure.

Referring to FIG. 1, a service providing system includes an externaldevice 100, a portable terminal device 200, and a web server 300. Theexternal device 100 is a device that can perform wired/wirelesscommunication, such as a smart TV, and further performs datacommunication with the portable terminal device 200 through wirelesscommunication. The external device 100 processes an image signalreceived from an external transmission device to output an image 110,and transmits data of an output image 110 to the portable terminaldevice 200. Accordingly, the portable terminal device 200 can display ona screen the same image 201 as the image 110 that is displayed on theexternal device 100.

More specifically, the external device 100 may receive a satellite,cable, or ground-wave broadcasting signal from the external transmissiondevice, or may receive an image signal through a source device, such asa web server, or a reproduction device, such as a Digital Versatile Disk(DVD) device, through at least one of CART, Audio-Visual (AV), HighDefinition Multimedia Interface (HDMI), component, and Universal SerialBus (USB) interfaces, through a reception module (not illustrated). Ifthe image signal is received through the reception module, the externaldevice 100 may process the image signal that is received through animage processor (not illustrated), and output the video/audio typeimage. Since the technology to output the video/audio type image throughsignal processing of the image signal received from the outside is wellknown, the detailed description thereof will be omitted.

On the other hand, the external device 100, which outputs the receivedimage signal as the video/audio type image, transmits image data that iscurrently output through the communicator (not illustrated) to theportable terminal device 200. Accordingly, the portable terminal device200 can display the same image 201 as the image 110 that is currentlydisplayed on the external device 100 on the screen.

A user may have an interest in the image 110 of the currently reproducedpicture while viewing the image 110 through the external device 100 orthe portable terminal device 200. As illustrated, the external device100 and the portable terminal device 200 may reproduce the same image110 or 201, and the user may be interested in a character that appearsin the corresponding image 110 or 201 while viewing the image 110 or 201through the external device 100 or the portable terminal device 200.Accordingly, the user may request a character search for thecorresponding image 110 or 201 through the portable terminal device 200.

According to an embodiment, if the user is interested in a characterthat appears in the image 110 or 201, the user may select apredetermined input of the portable terminal device 200. However, thepresent disclosure is not limited thereto, and in an embodiment the usermay touch the screen of the portable terminal device 200. If the inputor the touch is made, the portable terminal device 200 generates andstores a captured image 202 of the scene corresponding to a time whenthe input button or the touch is made. At this time, it is preferablethat the portable terminal device 200 detects at least one objectincluded in the captured image 202 and stores the detected objecttogether with the captured image 202. On the other hand, if the image110 or 201 that is viewed through at least one of the external device100 and the portable terminal device 200 is terminated, the user maystill select the captured image 202 stored in the portable terminaldevice 200.

If such a selection command for the captured image 202 is input, theportable terminal device 200 displays a task execution menu thatincludes the captured image 202 selected by the user and menuscorresponding to at least one object included in the correspondingcaptured image 202 on the screen. Thereafter, if at least one of themenus included in the task execution menu that is displayed on thescreen is selected by the user, the portable terminal device 200displays search result information of the object corresponding to themenu from the web server 300.

As described above, the portable terminal device 200 according to anembodiment of the present disclosure detects and stores the capturedimage 202 of the image 201 at the time when the user's selection commandis input and the object included in the corresponding captured image.Accordingly, after the image 201 that is currently viewed is ended, theuser can be provided with the search result information of the objectcorresponding to the concerned element among the objects included in thecaptured image 202 that is stored in the portable terminal device 200through the portable terminal device 200. Accordingly, the user'sinconvenience, which may be caused by forgetting of the concernedelement occurring during viewing the image or searching for informationon the corresponding concerned element with interception of viewing ofthe image that is currently being reproduced, can be solved. The usermay thus perform a search on an object in the captured image 202 inwhich the user is interested, substantially without interrupting theviewing of the image 110 on the external device 100. The user may alsothus perform the search and obtain search results without relying onmemory and without writing down anything.

According to another embodiment, if the user is interested in acharacter appearing in the drama, the user can select the correspondingcharacter from the image 201 that is displayed on the screen of theportable terminal device 200. If such a selection command is input, theportable terminal device 200 detects an object that is displayed in anarea selected by the user. Thereafter, the portable terminal device 200receives the search result information related to the correspondingobject from the web server 300, and displays the search resultinformation.

As described above, if the user's selection command is input, theportable terminal device 200 displays the search result informationrelated to the object that is displayed in real time on the areaselected by the user, and thus the user can be provided with theinformation on the image element in a state where the user views theimage 201 through the portable terminal device 200 in real time whilecontinuously viewing the image 110 that is currently been viewed throughthe external device 100.

Until now, the operation of the service providing system that includesthe external device 100, the portable terminal device 200, and the webserver 300 has been briefly described. Hereinafter, the operation of theabove-described portable terminal device 200 will be described indetail.

FIG. 2 is a block diagram of a portable terminal device 200 according toan embodiment of the present disclosure.

Referring to FIG. 2, the portable terminal device 200 may be a terminaldevice that can perform wireless communication, such as a smart phone ora tablet Personal Computer (PC). The portable terminal device 200includes a communicator 210, a display 220, an inputter 230, and acontroller 240. The communicator 210 performs communication with theexternal device 100. For this, the communicator 210 may include variouscommunication modules, such as a short-range wireless communicationmodule (not illustrated) or a wireless communication module (notillustrated).

Here, the short-range wireless communication module is a communicationmodule that performs wireless communication with the external device 100that is positioned within a short distance, and may be, for example,Bluetooth or Zigbee. The wireless communication module is a module thatis connected to an external network according to wireless communicationprotocols such as WiFi and the like, to perform communication. Inaddition, the wireless communication module may further include a mobilecommunication module that is connected to a mobile communication networkaccording to various mobile communication standards, such as 3^(rd)Generation (3G), 3^(rd) Generation Partnership Project (3GPP), and LongTerm Evolution (LTE), to perform communication.

The display 220 displays the image 201 that is received from theexternal device 100 through the communicator 210. Specifically, thedisplay 220 may be implemented by Organic Light Emitting Diodes (OLED),a Liquid Crystal Display (LCD), or the like. The display 220 may beimplemented in the form of a touch screen that forms a mutual layerstructure with a touchpad, and the touch screen may be configured todetect a touch input position, area, and pressure of a touch input. Theimage 201 that is displayed on the screen through the display 220 is thesame image as the image 110 that is currently being displayed on theexternal device 100. However, the present disclosure is not limitedthereto, and the image 201 may be a pre-stored image or an image relatedto a broadcast that is received from an external broadcastingtransmission device through a reception module (not illustrated).

The inputter 230 is an input means for receiving an input of a selectioncommand according to various user operations and transferring theselection command to the controller 240. Here, the input panel may be inthe form of a touch pad, a keypad having various kinds of function keys,numeral keys, special keys, character keys, or a touch screen.

The controller 240, which controls the overall operation of thecommunicator 210 and the display 220, perform an operation correspondingto an object that is included in the image 201 at a time when theselection command is input through the inputter 230. Further, if theuser's selection command is input through the inputter 230, thecontroller 240 generates a captured image 202 of the image 201 at thetime when the selection command is input and stores the captured image202 in the storage 250. The storage for storing the captured image maybe a nonvolatile memory, such as a flash memory.

If the user's selection command is input through the inputter 230, thecontroller 240 performs an operation corresponding to an object that isincluded in the image 201 at the time when the selection command isinput. Specifically, if the user's selection command is input throughthe inputter 230, the controller 240 generates the captured image 202 ofthe image 201 at the time when the user's selection command is input,and stores the generated captured image 202 in the storage 250. However,the present disclosure is not limited thereto. If a storage command forthe captured image 202 is input from the user, the controller 240 maystore the captured image 202 in the storage 250. According to variousembodiments, if the user's selection command is a command related to thegeneration of the captured image 202, the controller 240 may store thecaptured image 202 that is generated according to the user's selectioncommand in the storage 250. On the other hand, if the user's selectioncommand is a command related to the selection of a specific object thatis included in the image 201, the controller 240 may store the generatedcaptured image 202 in the storage 250 without any separate storagecommand.

Accordingly, If the user's selection command is input through theinputter 230, the controller 240 determines whether the input selectioncommand is a command related to the generation of the captured image 202or a command related to the selection of the specific object that isincluded in the image 201 while generating the captured image 202 of theimage 201 at the time when the selection command is input.

If the user's selection command is a command related to capturing of theimage 201 that is displayed through the display 220 as the result of thedetermination, the display 220 displays a task execution menu thatincludes the generated captured image 202 and menus corresponding to atleast one object that is included in the corresponding captured image202 on one area of the screen in accordance with a control command ofthe controller 240. Specifically, the controller 240 may detect theobject that is included in the captured image 202 according to thefollowing embodiment.

According to an embodiment, if the object that is included in thecaptured image 202 is a text image, the controller 240 may recognize thetext image using an analysis algorithm, such as an Optical CharacterReader (OCR). According to another embodiment, if the object that isincluded in the captured image 202 is a face image, the controller 240may recognize the face image using an analysis algorithm, such as aPrincipal Component Analysis (PCA). According to still anotherembodiment, if the object that is included in the captured image 202 isa thing, the controller 240 may recognize the corresponding thing usingan object tracking algorithm, such as an edge-based algorithm. At thistime, the controller 240 may recognize the corresponding thing and abackground using a color detection algorithm together with the objecttracking algorithm. In the present disclosure, the object recognitionalgorithm has been briefly mentioned, but the present disclosure is notlimited thereto. The object that is included in the captured image 202may be recognized using other algorithms.

If at least one object that is included in the captured image 202 isdetected through the object recognition algorithm, the controller 240generates a task execution menu that includes a menu corresponding tothe detected object. Accordingly, the display 220 can display the taskexecution menu that includes the generated captured image 202 and themenu corresponding to the object that is detected from the correspondingcaptured image 202 on one area of the screen as described above.Further, the display 220 may display the same image 201 as the image 110that is currently being reproduced on the external device 100 on theremaining area. On the other hand, if one of the menus included in thetask execution menu that is displayed on one area of the screen isselected by the user, the controller 240 may perform an operationcorresponding to the selected menu.

According to an embodiment, a search window object may be included inthe captured image 202 that is generated at the time when the selectioncommand is input. As described above, if the search window object isincluded in the captured image 202, the controller 240 controls thedisplay 220 to display the task execution menu that includes the searchmenu corresponding to the search window object. Accordingly, the display220 displays the task execution menu that includes the search menucorresponding to the search window object on one area of the screentogether with the captured image 202. Additionally, the display 220 maydisplay a storage menu for storing the corresponding captured image 202on the one area of the screen together with the task execution menu thatincludes the search menu corresponding to the search wind object.

As described above, if the task execution menu that includes the searchmenu and the storage menu that are displayed on the one area of thescreen is displayed, the user may select at least one menu of thedisplayed menus. According to the various embodiments, if the searchmenu is selected, the display 220 displays the search screencorresponding to the search window object according to the controlcommand of the controller 240. Accordingly, the user can receive theresult of the search for the scene on which the concerned element occursin the currently viewed image 201 through the search screen that isdisplayed on the screen.

On the other hand, if the storage menu is selected, the controller 240stores the corresponding captured image 202 in the storage 250. As thecaptured image 202 is stored in the storage 250, the user can overcomethe inconvenience which is caused by forgetting of the element ofinterest, the interest occurring during viewing the element image thatoccurs in the image 201 that is currently viewed or searching forinformation on the corresponding element with interception of viewing ofthe image 201 that is currently being reproduced.

Hereinafter, the above-described embodiment will be described in detailwith reference to FIGS. 3A to 4C.

FIGS. 3A to 3C are views explaining generation of a captured image and amenu in a portable terminal device according to an embodiment of thepresent disclosure, and FIGS. 4A to 4C are views explaining performingan operation corresponding to a menu displayed on a screen of a portableterminal device according to an embodiment of the present disclosure.

Referring to FIG. 3A, the portable terminal device 200 may display thesame image 300 as that displayed on the external device 100. The image300 may be, for example, an advertisement for a product or service.Accordingly, the user can view the advertisement image 300 through atleast one of the external device 100 and the portable terminal device200. If the contents of the advertisement image 300 interest the user,then the user viewing the advertisement image 300 may select a menubutton (not illustrated) or touch the screen on which the advertisementimage 300 is displayed. If the selection command as described above isinput, the controller 240 determines that the input selection command isa selection command related to capturing, and generates a captured image320 of the advertisement image 300 at the time when the selectioncommand is input from the user.

Thereafter, the controller 240 reduces a size of the generated capturedimage 320. Accordingly, referring to FIG. 3B, the captured image 320 isreduced to a predetermined size. If the size of the captured image 320is reduced as described above, the display 220 displays a thumbnailimage 330 of the reduced captured image 320 on one area of the screen.Accordingly, referring to FIG. 3C, the display 220 can display thereduced captured image 320 on, for example, the right upper end portionof the screen as the thumbnail image 330. Of course, the presentdisclosure is not limited thereto; for example, the controller 240 maydetermine and locate the reduced captured image 320 in an area ofdisplay 220 least likely to include content of interest, such as an areaof least motion.

On the other hand, if the captured image 320 of the advertisement image300 at the time when the selection command is input from the user isgenerated, the controller 240 may detect the object that is included inthe captured image 320 through analysis of the captured image 320. Asdescribed above, the controller 240 may detect the object that isincluded in the captured image 320 through the object recognitionalgorithm. As described above, if the search window object 310 isdetected through the object recognition algorithm, the controller 240generates the task execution menu 340. Here, the task execution menu 340may include a search menu 341 corresponding to the detected searchwindow object 310 and a storage menu 342 for storing the captured image320. Thereafter, the display 220 displays the task execution menu 340 onthe one area of the screen together with the thumbnail image 330 of thecaptured image 320 in accordance with the control command of thecontroller 240.

Accordingly, referring to FIG. 3C, the display 220 may display the taskexecution menu 340 that includes the thumbnail image 330 of the capturedimage 320, the search menu 341 for the search window object 320 detectedfrom the captured image 320, and the storage menu 342 for storing thecaptured image 320 on the right upper end area of the screen, and maycontinue to display the same image 350 as the image 110 that iscurrently being reproduced on the external device 100 in the remainingarea of the screen.

As described above, if one of the search menu 341 and the storage menu342 included in the task execution menu 340 is selected by the user in astate where the thumbnail image 330 and the task execution menu 340 aredisplayed on the one area of the screen, the controller 240 may performthe operation corresponding to the selected menu.

According to an embodiment, if the search menu 341 is selected by theuser, the controller 240 controls the display 220 to display the searchscreen related to the selected search menu 341. Specifically, if thesearch menu 341 for the search window object 310 is selected, thecontroller 240 requests a search for a keyword that is included in thesearch window object through accessing the web server 300 related to thesearch window object through the communicator 210. Thereafter, if thesearch result according to the search request is received from the webserver 300, the display 220 may display the search screen 341 for thereceived search result. Accordingly, referring to FIG. 4B, the searchscreen 360 for the keyword included in the search window object 310 maybe displayed on the screen of the portable terminal device 200.Accordingly, the user can be provided with the scene on which theelement of interest occurs in the image 350 that is currently viewed orthe search result for the keyword through the search screen 360 that isdisplayed on the screen.

On the other hand, if the storage menu 342 for storing the capturedimage 320 is selected, the controller 240 controls the storage 250 tostore the captured image 320 that is displayed as the thumbnail image330. According to the control command, the storage 250 stores thecaptured image 320 that is displayed on the screen. Accordingly,referring to FIG. 4C, the captured image 320 may be stored in thestorage 320 together with other captured images. However, the presentdisclosure is not limited thereto, and the storage menu 342 for storingthe captured image 320 need not be separately provided. In this case, asdescribed above with reference to FIGS. 3A to 3C, the controller 240 canstore the captured image 320 generated at the time when the selectioncommand is input from the user in the storage 250 without any separateoperation command.

As described above, as the captured image 320 is stored in the storage250, the user can solve the inconvenience which is caused by forgettingof the element of interest occurring during viewing the element imagethat occurs in the image 300 that is currently viewed or searching forinformation on the corresponding concerned element with interception ofviewing of the image 300 that is currently being reproduced.

According to another embodiment, an object related to a phone number maybe included in the captured image 320 that is generated at the time whenthe selection command is input. As described above, if the objectrelated to the phone number is included in the captured image 320, thecontroller 240 controls the display 220 to display a call connectionmenu corresponding to the phone number. Accordingly, the display 220displays the task execution menu that includes the captured image 320and the call connection menu corresponding to the phone number on theone area of the screen.

Accordingly, the user can solve the inconvenience that iscaused by attempting the call connection through direct pressing of thebutton corresponding to the phone number displayed on the screen. Thisembodiment thus relieves the user of the troubles of needing toremember, record, and manually enter the displayed telephone number.

For example, the portable terminal device 200 may display the sameimage, for example, a home shopping picture, as that displayed on theexternal device 100. Accordingly, the user can view the home shoppingpicture through at least one of the external device 100 and the portableterminal device 200. If a phone number for an automated order forordering a home shopping product appears on the screen while viewing thehome shopping picture, the user may press a menu button (notillustrated) or touch the screen on which the home shopping picture isdisplayed. If such a selection command is input, the controller 240determines that the input selection command is a selection commandrelated to capturing, and generates a captured image 320 of the homeshopping picture at the time when the selection command is input by theuser with a reduced picture size. Also, the controller 240 detects thephone number for the automated order of the home shopping product fromthe captured image 320 through the object recognition algorithm, andgenerates a task execution menu that includes a call connection menucorresponding to the detected phone number for the automated order andthe storage menu 342 for storing the captured image 320. Thereafter, inaccordance with the control command of the controller 220, the display220 displays the thumbnail image 330 of the captured image 320 with areduced size and the task execution menu on the one area of the screenand displays the same image 350 as the image 110 that is currently bereproduced on the external device 100 on the remaining area of thescreen.

As described above, if the call connection menu, which is included inthe task execution menu together with the storage menu 342, is selectedby the user, the controller 240 attempts an automated call connectionusing the phone number included in the captured image 320. Accordingly,the user can order the home shopping product without manually attemptingthe call connection by directly pressing the buttons corresponding tothe phone number for the automated order that is displayed on thescreen.

According to still another embodiment, an object related to a characterimage or a text may be included in the captured image 320 that isgenerated at the time when the selection command is input. If the objectrelated to the image or the text is included in the captured image 320,the controller 240 controls the display 220 to display a search menu forthe image or the text. Accordingly, the display 220 displays the taskexecution menu 340 that includes the captured image and the search menu341 for the image or the text on one area of the screen. Thereafter, ifthe search menu 341 for the image or the text that is included in thetask execution menu 340 displayed on the screen is selected by the user,the controller 240 performs a search for the image or the text andcontrols the display 220 to display the result of the search.Accordingly, the display 220 can display the search result for the imageor the text.

For example, the portable terminal device 200 can display a same dramaas that displayed on the external device 100. Accordingly, the user canview the drama through at least one of the external device 100 and theportable terminal device 200. During the viewing of the drama, the usermay be interested in learning about a character that appears in thedrama. If such an element of interest occurs, the user may press a menubutton (not illustrated) or touch the screen on which the drama isdisplayed. If such a selection command is input, the controller 240generates a captured image 320 of the drama at the time when theselection command is input, and reduces the size of the captured image320. Also, the controller 240 may detect at least one object related toa character that is included in the captured image 320 through theobject recognition algorithm related to face recognition. If the objectrelated to the character is detected, the controller 240 generates thetask execution menu 340 that includes the search menu 341 correspondingto the detected object related to the character and the storage menu 342for storing the captured image 320. Thereafter, in accordance with thecontrol command of the controller 240, the display 220 displays thethumbnail image 330 of the captured image 320 with a reduced size andthe task execution menu 340 on the one area of the screen and displaysthe same image 350 as the image 110 that is currently be reproduced onthe external device 100 on the remaining area of the screen.

If the search menu 341 that is included in the task execution menu 340is selected by the user in a state where the thumbnail image 330 and thetask execution menu 340 are displayed on the one area of the screen, thecontroller 240 requests a search for the character corresponding to thesearch menu 341 through accessing the predetermined web server 300.Thereafter, if the search result according to the character search isreceived from the web server 300, the display 220 may display the searchscreen 360 for the received search result. Accordingly, the user can beprovided with the search result for the character appearing in the dramathat is currently viewed through the search screen 360 that is displayedon the screen.

Referring to FIG. 10, the portable terminal device 200, which interlockswith the external device 100, displays the same image 201 as the image110 that is currently displayed on the external device 100 at operationS1010. If the selection command is input from the user at operationS1020, the portable terminal device 200, which displays the same image201 as the image 110 that is displayed on the external device 100,generates and stores the captured image 202 of the image 201 at the timewhen the selection command is input at operation S1030. However, thepresent disclosure is not limited thereto. If the storage command forthe captured image 202 is input from the user at operation S1020, theportable terminal device 200 may store the corresponding captured image202. In the present disclosure, if the selection command is input fromthe user at operation S1020, the captured image 202 of the image 201 atthe time when the selection command is input is generated and stored,which will be described.

If the captured image 202 of the image 201 at the time when theselection command is input is generated and the generated captured imageis stored, in accordance with the user's selection command at operationS1020, the portable terminal device 200 performs the operationcorresponding to the object included in the image 201 at the time whenthe selection command is input at operation S1020. Specifically, theportable terminal device 200 checks whether the selection command thatis input by the user through the operation S1020 is a selection commandrelated to capturing or a command related to the selection of a specificobject included in the image 201 at operation S1040. If the command isdetermined to be the selection command related to capturing as theresult of checking, the portable terminal device 200 displays atoperation S1050 a task execution menu that includes a menu correspondingto at least one object included in the captured image 202 on one area ofthe screen, and if one of the menus included in the task execution menuthat is displayed on one area in operation S1050 is selected, theportable terminal device 200 performs the operation corresponding to theselected menu at operation S1060.

According to an embodiment, the search window object may be included inthe captured image 202 that is generated at the time when the selectioncommand is input at operation S1020. As described above, if the searchwindow object is included in the captured image 202, the portableterminal device 200 generates the task execution menu that includes thesearch menu corresponding to the search window object on one area of thescreen. Also, the portable terminal device 200 reduces the size of thecaptured image 202 so that the captured image 202 that is generated atthe time when the selection command is input at operation S1020 isdisplayed on one area. Thereafter, the portable terminal device 200displays the task execution menu that includes the thumbnail image ofthe captured image 202 with a reduced size and the search menucorresponding to the search window object that is included in thecorresponding captured image 202 on one area of the screen.

Specifically, ifthe search menu corresponding to the search window object is selected,the portable terminal device 200 requests the search for the keywordthat is included in the search window object through accessing the webserver 300 related to the search window object. Thereafter, if thesearch result according to the search request is received from the webserver 300, the portable terminal device 200 may display the searchscreen for the received search result. Accordingly, as shown in FIGS. 4Ato 4C, the user can be provided with the scene on which the element ofinterest occurs in the image 300 that is currently viewed or the searchresult 360 for the keyword through the search screen 341 that isdisplayed on the screen.

According to another embodiment, the search window object 310 may beincluded in the captured image 320 that is generated at the time whenthe selection command is input. As described above, if the search windowobject 310 is included in the captured image 320, the portable terminaldevice 200 may display the task execution menu 340 that includes thethumbnail image 330 of the captured image 320 and the call connectionmenu corresponding to the phone number on one area of the screen, andmay display the same image 350 as the image 110 that is currently beingreproduced in the external device 100 in the remaining area.

For example, the portable terminal device 200 may display the same homeshopping picture 500 as the image 110 displayed on the external device100. Accordingly, the user can view the home shopping picture 500through at least one of the external device 100 and the portableterminal device 200. If a phone number 510 for an automated order forordering a home shopping product appears on the screen while viewing thehome shopping picture 500, the user may press the menu button (notillustrated) or touch the screen on which the home shopping picture 500is displayed. If such a selection command is input, the controller 240determines that the input selection command is the selection commandrelated to capturing, and generates the captured image 202 of the homeshopping picture 500 at the time when the selection command is input bythe user with a reduced picture size. Also, the portable terminal device200 detects the phone number 510 for the automated order for orderingthe home shopping product from the captured image 202 through the objectrecognition algorithm, and generates the task execution menu thatincludes the call connection menu corresponding to the detected phonenumber for the automated order. Thereafter, the portable terminal device200 displays the thumbnail image of the captured image 202 with areduced size and the call connection menu on the one area of the screenand displays the same image 350 as the image 110 that is currently bereproduced on the external device 100 on the remaining area of thescreen.

As described above, if the call connection menu, which is included inthe task execution menu, is selected by the user in a state where thethumbnail image and the task execution menu 340 are displayed on the onearea of the screen, the portable terminal device 200 attempts theautomated call connection using the phone number 510 included in thecaptured image 320. Accordingly, the user can order the home shoppingproduct without manually attempting the call connection by directlypressing the buttons corresponding to the phone number 510 for theautomated order that is displayed on the screen.

According to still another embodiment, the object related to thecharacter image or the text may be included in the captured image 320that is generated at the time when the selection command is input atoperation S1020. If the object related to the image or the text isincluded in the captured image 320, the portable terminal device 200displays the task execution menu 340 that includes the captured image320 and the search menu for the image or the text on one area of thescreen. Thereafter, if the search menu for the image or the text that isincluded in the task execution menu 340 displayed on the screen isselected by the user, the portable terminal device 200 performs thesearch for the image or the text and controls the display 220 to displaythe result 360 of the search.

For example, the portable terminal device 200 may display the same drama800 as that displayed on the external device 100. Accordingly, the usercan view the drama 800 through at least one of the external device 100and the portable terminal device 200. During the viewing of the drama800, the user may be interested in learning more about a character 810that appears in the drama 800. If such an element of interest occurs,the user may press a menu button (not illustrated) or touch the screenon which drama 800 is displayed. If such a selection command is input,the portable terminal device 200 generates the captured image 320 of thedrama 800 at the time when the selection command is input at operationS1020, and reduces the size of the captured image 320. Also, theportable terminal device 200 may detect at least one object related to acharacter 810 that is included in the captured image 320 through theobject recognition algorithm related to face recognition.
